SPRINKLING-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 564,906, dated July 28,1896.

Application filed November 9, 1895. Serial No. 568,474. (No model.)

To all whom it may concern:

Be it known that I, CHARLES F. VAN CAMP, a citizen of the United States,residingin Philadelphia, Pennsylvania, have invented certainImprovements in sprinkling-Nozzles, of which the following is aspecification.

One object of my invention is to construct a sprinkling or sprayingnozzle whereby the stream of water or other liquid will be broken up andwidely spread in the form of a thin sheet or spray, a further objectbeing to control the extent and direction of the discharge as may bedesired. These objects I attain in the manner hereinafter set forth,reference being had to the accompanying drawings, in which-- Figure 1 isa longitudinal section of a lawn sprinkler having a sprinkling orspraying nozzle constructed in accordance with my invention. Fig. 2 is asectional plan view of the same, and Figs. 3 and 4 are perspective viewsof difierent forms of spraying-tongues which may be used.

A represents a casin g, which may be of any desired size, shape, orconfiguration, said casing having at the base a threaded opening a forthe reception of a nipple or coupling upon the hose or otherpipe,'whereby the supply of water is conveyed to the sprinkler.

The casing A is preferably inclined upwardly from the receiving end a,being supported in this inclined position by suit-able legs or props b,and in the casing is an upwardly inclined passage d, reduced in diameterat the upper end, as shown at cl, so as to project into a chamber B atthe upper end of the casing a forcible jet of water.

Hung to a pivot'pin f, which crosses the chamber 13, is a tongue D,terminating at the outer end in a pair of curved and outwardlyflaringwings g, as shown in Fig. 2, the pivotpin 3 being located directly inline with the jet issuing from the contracted orifice d and being sodisposed in respect to the tongue D that the greater portion of thelength of the latter is outwardly beyond the pivot. The

effect of this construction is that when the tongue is exposed to theaction of the jet a rapid and constant vibration of the same in thechamber B results and the water issuing from the mouth of the chamber Bis spread laterally in the form of a thin sheet or spray, the mouth ofthe chamber B being widened to permit of the swinging movement of thetongue, which is caused by the constant shifting of the preponderatingforce of the jet from one side of the tongue to the other, for when thetongue reaches an inclinedposition, which causes the exercise of greaterforce upon one side than upon the other, it is thereby forced to theopposite inclined position, and the force of the jet being thus shiftedit is at once forced back again and the vibrations are thus constantlykept up.

It might be thought that the tongue D would assume a central position,so as to evenly divide the jet and be thereby retained fixedly in thiscentral position, but this is simply a theoretical possibility, andnever results in practice.

The direction of the sheet or spray issuing from the sprinkler may, ingreat measure, be governed by the shape of the flaring wings g of thetongue. For instance, if the said wings are of the full width of thetongue and practically fill the chamber B from top to bottom, the sheetor spray will be thrown laterally in both directions, and but little, ifany, will be projected directly in front of the sprinkler, but if theflaring wings are reduced at top and bottom, as shown, for instance, at11 in Fig. 1, some of the water will escape above and be low said wingsand will be projected directly forward, while if the wings have centralslots formed in them, as shown, for instance, at m m in Fig. 4, thevolume of water projected directly forward may be caused to equal orexceed that which is thrown out laterally.

In carrying out my invention any desired form of casing for containingthe vibrating tongue maybe used. For instance, instead of a structuresuch as I have shown, and which is adapted to rest upon the lawn, thecasing vance of said jet-opening, the pivotal axis of the tongue beingin the path of the jet issuing from the opening but extendingtransversely across the same, substantially as specified.

2. A spraying-nozzle having a jet-opening I therein and a pivoted tonguesupportedin ad- Vance of said jet-opening, the pivotal axis of thetongue being in the path of the jet issuing from the opening butextending transversely across the same, and being located nearer to theinner end of the tongue than to the outer end of the same, substantiallyas specified.

3. A spraying-nozzle having a j etopening therein and a pivoted tonguesupported in advance of said jet-opening, the pivotal axis of the tonguebeing in the path-of the jet issuing from the opening but extendingtransversely across the same, said tongue being laterally flared at theouter end, substantially as specified.

4. A spraying-nozzle having a jet-opening therein and a pivoted tonguesupported in advance of said jet-opening and laterally flared at theouter end, the pivotal axis of the tongue being in the path of the jetissuing from the opening but extending transversely across the same, andbeing nearer to the inner end of the tongue than to the outer end of thesame, substantially as specified.

. therein and a tongue pivoted in advance of said jet-opening and inline with the jet issuing therefrom, said tongue being laterally flaredat the outer end and having said flared portion centrally recessed orslotted so as to permit of a forward discharge of fluid through thesame, substantially as specified. 7. A spraying-nozzle consisting of acasing having at the base an opening for'the reception of the supplyhose or pipe, and having also an upwardly-inclined passage terminatingin a jet-opening, with a tongue pivoted in advance of said jet-openingand in line with the jet issuing therefrom, the pivotal axis of thetongue extending transversely across the jet, substantially asspecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
